e83d74f626 This is the first patch to put the needed bits in place to eventually allow code 
to be aligned with optimal nops.  This patch does not change any functionality
and when the compiler is changed to use EmitCodeAlignment() it should also not
change the resulting output.  Once the compiler change is made and everything
looks good the next patch with the table of optimal X86 nops will be added to
WriteNopData() changing the output.  There are many FIXMEs in this patch which
will be removed when we have better target hooks (coming soon I hear).

normal form of .file would fail if the filename had a weird character
in it.

6a715dccdf llvm-mc: MCStreamer cleanups. - Remove EmitLocalSymbol, this is unsupported for now. 
- Switch Emit{CommonSymbol,Zerofill} to take alignment in bytes (for consistency).

2a2459a291 llvm-mc: .lsym is more unsupported than unimplemented, pending a use case appearing. 
Also, all one of the file level flags are implemented.

42a39d038a llvm-mc: Support .zerofill emission. 
- I'm still trying to figure out the cleanest way to implement this and match the assembler, currently there are some substantial differences.

582d61026d llvm-mc/Mach-O: Preliminary support for indirect symbols. 
- The indirect table itself isn't being filled in yet.

 - This isn't factored properly and is rather FIXMEd, but at the moment I'm more
   focused on figuring out what it needs to do.

04a1158d13 llvm-mc/Mach-O: Support symbol attributes. 
- This is mostly complete, the main thing missing is .indirect_symbol support
   (which would be straight-forward, except that the way it is implemented in
   'as' makes getting an exact .o match interesting).

d1859474a7 llvm-mc/Mach-O: Improve symbol table support: 
- Honor .globl.

 - Set symbol type and section correctly ('nm' now works), and order symbols
   appropriately.

 - Take care to the string table so that the .o matches 'as' exactly (for ease
   of testing).
